Ultra-wide high-lift synchronous steering insecticide spraying machine rack

Abstract

The invention discloses an ultra-wide high-lift synchronous steering insecticide spraying machine rack. Compared with the prior art, the ultra-wide high-lift synchronous steering insecticide spraying machine rack has the advantages that the height of a spraying bracket can be improved twice by using a common hydraulic oil cylinder in a manner that a lift oil cylinder (29) pushes a lift shaft (24) and then drives a lift wheel (23) and a chain (28) drives the spraying bracket (9) according to the movable block principle; meanwhile, the spraying bracket (9) can keep a high balancing state through a shock absorber (18) according to the balance principle, and therefore the ultra-wide folding spraying bracket can be installed and the efficiency of an insecticide spraying machine can be higher; a hydraulic oil cylinder communicated with a tractor front-wheel steering oil cylinder is arranged on a side face of an L-shaped traction frame (2), the steering of the insecticide spraying machine rack can be coincident with the steering of tractor front wheels, and therefore the insecticide spraying machine can steer with the minimum radius and damage to crops when the insecticide spraying machine steers can be reduced.

Description

technical field [0001] The invention relates to an agricultural machine, in particular to an ultra-wide and high-lift synchronously steering sprayer machine frame. Background technique [0002] Pesticide sprayer is an indispensable agricultural machinery in agricultural production. Especially for large-scale crops, using efficient sprayer can save a lot of manpower and material resources. However, it is difficult for the current sprayer to be suitable for different crops. The needs of various growth stages, such as: corn and sorghum grow relatively high in the middle and late stages of growth, and general sprayers use hydraulic cylinders to lift the height of spray racks. The lifting height of ordinary hydraulic cylinders is very limited and cannot be raised. To the corresponding height, it is impossible to meet the needs of high-stalk crops spraying. In order to meet the needs of high-stalk crops in the middle and late stages of growth, it must be equipped with a sprayer su...

[0002] Pesticide sprayer is an indispensable agricultural machinery in agricultural production. Especially for large-scale crops, using efficient sprayer can save a lot of manpower and material resources. However, it is difficult for the current sprayer to be suitable for different crops. The needs of various growth stages, such as: corn and sorghum grow relatively high in the middle and late stages of growth, and general sprayers use hydraulic cylinders to raise and lower the height of spray racks. The lifting height of ordinary hydraulic cylinders is very limited and cannot be raised To the corresponding height, it is impossible to meet the needs of high-stalk crop spraying. In order to meet the needs of high-stalk crops in the middle and late stages of growth, it must be equipped with a sprayer suitable for high-stalk crops. In addition, in order to meet the needs of high efficiency, often The sprayer The spray racks are also made wider and wider, but if the sprayer spray racks are made too wide, it will be difficult to maintain balance when walking on the farmland, which also brings inconvenience to agricultural production
